Why isn't the script displaying text?

I'm trying to review and practice conditional statements. I made an if else statement that will Display a string in a paragraph depending on the conditional value of the variable "hungerLevel". I can get it done easily with document.write but I'm aware this command is only for testing purposes and not actual display of text. Why isn't my code working? Id appreciate the help! <p id="text"></p>  <script> var hungerLevel= prompt("How hungry is Natsuki?") if (hungerLevel<10) { document.getElementById('text').innerHTML("Natsuki isnt hungry."); } else { document.getElementById('text).innerHTML ("Natsuki is hungry! Let's get her some treats!"); } </script> </body>

Look at the code. I corrected some of the mistakes like if you want to compare numbers stored in the prompt variable you need to convert it to number, also missing quotation mark when you get an element 'text' by id and setting the innerHTML. Hope it helps you. https://code.sololearn.com/W1UYauF6ozRG/?ref=app

Just to explain a little. 1. innerHTML isn't a function, so you're assigning a value to it. In this case, you'll use ###.innerHTML = "whatever" instead of ###.innerHTML("whatever"). 2. Instead of constantly searching for that element, assign it to a variable so it's only having to do that once. Good practice to save on performance. Example: var el = document.getElementById('text'); Then you can just use the variable to reference it instead of always searching for it each time.
